摘要

计算了 LIGO 旅行者引力波探测器的弹性光学模式和斯托克斯光学模式的不稳定组合数量、频率以及反射镜弹性模式位移矢量的空间分布。考虑到参数不稳定性的方位角条件，计算了九阶以下不稳定模式的重叠因子值。还分析了镜面材料的杨氏模量随温度变化对法布里-珀罗腔中不稳定模式数量的影响。

Suppression of the Effect of Parametric Instability in the LIGO Voyager Gravitational Wave Detector

The number of unstable combinations of elastic and Stokes optical modes of the LIGO Voyager gravitational wave detector, frequencies and spatial distributions of displacement vectors of elastic modes of the mirrors were calculated. The values of overlap factors for unstable modes up to ninth-order optical modes were calculated, taking into account the azimuthal condition of parametric instability. An analysis of the influence of the temperature dependence of the Young’s modulus of the mirror material on the number of unstable modes in the Fabry–Perot cavity was performed.
